AC InfinityFan Speed Controller for 100 to 125V AC Axial Muffin Cooling Fans, Dual Connector, for DIY Cooling Ventilation Exhaust Projects

Love this brand, easy to setup and to use, worked out the box. looks nice, matte housing with a gloss faced nob matte sides comfy grip and feel. The nob turns smoothly, there’s no play, responsive, there’s no delay. Comes with mounting bolts and nuts and wood screws of nice quality, black coated matching the color of everything else. Lovely

Reduced fan noise.

I bought two AC Infinity fans for a cooling system I built into my tv stand. They move a lot of air, but they are loud when plugged in directly to an outlet. This module allows you to adjust speed and get the cooling you want, at a desired speed/sound level.

This review is for the AC infinity 120 mm AC fan and controller. They are a perfect combination and as a bonus, the controller comes with cabling for 2 fans, so it can daisy chain at least 2 together. I needed mine to point in a specific direction, in my case, I use to help cool an air pump for my plants. This unit works perfectly and the frame I made for mine makes it even better. It's very adjustable now and real easy to adjust flow. I've been running it on the lowest setting and it seems to be right on. It's nice to know that there's plenty more power if I need it. If you need a fan that is durable, compact and versatile, this is it!!!

It doesn't always turn off when you turn the dial off. on those occasions I just unplug it. It also makes erratic jumps try turning it up a little same speed, move it father then full blast can be annoying, It also feels quite flimsy. But when its not acting up I can be in the same room without having to adjust everything else for the volume. I got to buy a knew one when it's acting weird itgets hoy to the touch, Thats just a fire waiting to happen.

Use to control two high RPM AC Infinity muffin fans used in a chicken coop for fresh air. Works great and offers good modulation of the fans. Can’t complain at all. Good product so far, in an austere environment (a dusty coop in AK temperatures).

Started building a kegerator and needed some fans to help push some air around inside the fridge. Hooked up the fans and controllers and everything works without any issues. Fans are really quiet and can really move some air. The controller is the best part. Dial in the speed and let it run. Everything is built with some seriously good quality for the money. Any future projects I have that will need some fans I will definitely use these guys. Fast shipping and again product is honestly the beat I have seen in a long time. Happy to see companies like this still making great quality products at an affordable price point.

I had purchased an AC Infinity Fan with a fan speed controller about 8 months ago. The fan worked great, but the controller did not work very well. The fan only turned on at about the 60% mark and would not run at slower speeds. Finally, the controller stopped working all together. I purchased another AC Infinity Fan with fan speed controller to replace the first one. The speed controller that came with the new fan has been redesigned in works perfectly. It worked so well that I purchased a dual controller and am now using both the old fan and new fan with the newly designed dual controller.
